INSTANTAN EOUS WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 639,478, dated December19, 1899. Application filed 111116 5, 1899. Serial No. 719,432. (Nomodel.)

To all whom it may concern.-

Beit known that I, GEORGE WILSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Tater-Heaters, of whichthe following is a specication.

.My invention relates to improvements in that class of devices forheating water which are known generally as instantaneous water-heatersand which are used in combination with bath-tubs and sinks and in whichthe water is distributed over a large heated area in a short space oftime, means being provided for the free circulation of both water andheated air.

The object of my improvements is to provide a device of this characterwhich will combine with a simple construction advantages of thoroughdistribution of the water, quick circulation of the hot air, and aprotection of the parts most exposed to the heat from the burner.

In the accompanying drawings, forming part of this application, I haveshown my improvements in a heater in which the heat is furnished from agas jet or burner; but it will be understood that I do not limit myselfto such application, as the chief features of my invention are equallyapplicable to a burner having coal, gasolene, or other fuel.

In said drawings, Figure 1 is a vertical section of the heater complete.Fig. 2 is a detailin elevation of an air-draft regulator. Fig. 3 is aplan view of a water-pan. Fig. 4 is a detail in section of a cup anddome in the upperpart of the heater. Fig. 5 is a top plan of the burner.Fig. v6 is a top plan view of one-halt' of the upper plate. Fig. 7 4isaseotion of the plate shown in Fig. 6. Fig. 8 is a top plan view ofonehalf of the lower plate. Fig. 9 is a top plan view of a section ofthe middle plate.

Like reference-numerals indicate like parts in the several views.

Referring to the drawings, 10 represents a cylindrical jacket whichsurrounds the heater, is made of any suitable material, and is providedwith a top or cover 102L and near its lower edge 4with openings orperforations 10b, through which air is admitted for circulation aroundthe burner. For convenience the jacketlO is preferably made in twosections, which are bolted together, as shown. Secured in the lower partof the 'jacket by means of arms 11c is an ainular burner 1l, made ofiron and preferably cast in two sections secured together by means of.bolts or rivets passing through suitable lugs 11b. The lower 'portionof the burner is formed with a branch pipe l1, through which thecombustible fluid is conducted to the burner, the outer end of said pipebeing formed daring and with its edges registering with an opening cutin the side of the jacket for the introduction of the gas-pipe nozzle21. The top of the burneris provided with a double row of holes 1l,through which thegas escapes into the combustion-chamber formed betweenthe burner and the dome 13. In the center of the burner is a collar 11,through which the air passes upwardlyinto the said combustion-chamber.Circulation of air around the burner is secured by the fact that thediameter of the burner is less than the diameter of the inner cylinder12, which surrounds the upper porrtion of the burner, as shown in Fig.1.

The cylinder 12 is preferably formed in two sections, as shown, and isprovided at different points with inwardly-bent annular ribs 12, 12b,and 12 to furnish supports for the top plate 17, middle plate 16, andlower plate 15, respectively. The lower edge of the cylinder is bentupwardly to embrace the lower edge of the dome 13 and therewith to forma tight joint. In the lower part of the cylinder is an opening 12d forthe introduction of the hot-water-discharge pipe or cock.

The dome 13 is formed with sloping sides, is open at the top, and aroundits upper edge is provided with an annulargutter or groove 13thSupported over the open mouth of the dome by legs 14 is a water-pan 14,in the bottom and near the outer edge of which is an annular groove 14h,which is perforated to permit the escape of the water from the pan uponthe dome and into the gutter 13a in said y dome.

Resting on the rib 12 is a circular plate 15, formed with corrugated orfluted edges 15d, having its center depressed and perforated, as at 15,and provided with an annular groove 1bb and with a series of openings15C, the latter being preferably formed by punching up- IOO wardly themetal, thus leaving raised edges, which prevent the water from runningdown through said openings in its ilow over the surface ofthe plate.From the depressed center this plate slopes downwardly to its outeredge, thus causing the water to traverse the surface of said plate fromcenter to circumference, except so much of it as escapes through thesmall openings in the center. Above the plate 15 and resting on thevflange 12b is a second plate 16, having a central opening 16 and nearits outer edge a plurality of upwardly-punched openings 16 and with anannular groove 16". The edges of this plate are plain, as shown in Fig.9, so that all water dropped upon it escapes through the central opening16, the plate sloping toward such opening, and the upturned edges aroundthe openings 16C preventing the escape of any water therethrough. Abovethe plate 16 is the top plate 17, which is formed with a plurality ofopenings 17, an annular groove 17, and fluted outer edge 17C, the mannerof forming the openings 17n being the saine as with thecorrespondingopenings in the plates 15 and 16. Secured to the upper side of the plate17 at its center is a cup 18, in one side of which is a suitable openingfor the admission of the water-supply pipe 20. The lower edge of thiscup is serrated or formed with teeth 18, the spaces therebetweenpermitting the escape of the water upon the plate 17, over the surfaceof which it flows by gravity. Surrounding the cup 1S and having itslower edges resting in the groove 17b of the plate 17 is a dome 19,having an open top and having an opening in its side for the passage ofthe pipe 20. The waste products of combustion or heated air pass outthrough this dome after traversing the cylinder from bottom to top inthe direction and along the lines indicated by the arrows.

In order that the admission of air to the pipe 11c may be regulated, Iprovide a plate 23, which fits over the opening in the side of thecylinder through which the pipe 21 passes, said plate having thereinopenings which are normally covered bya rotatable damper 23, by whichthe size of the opening is regulated in a well known manner. Extendingupwardly from the gas-supply pipe21 is a small pipe 22, provided with asuitable cock, and the upper end of said pipe extending within thecylinder at a point near the burner, said pipe serving as a pilot-tubefor igniting the gas at the burner in a manner well known in devices ofthis character.

In operation water is conveyed to my improved heater through the pipe 2Ofrom any suitable source of supply, the stream being thrown into the cup18, from which it escapes, as heretofore described. Thewater then fl owsdownwardly over the plate 17 into the groove 17b under the edges of thedome 19 and falls from the corrugated periphery of said plate upon theplate 16 at its outer edge. After flowing into the groove 16b it passesdownwardly and out of the central opening 16 upon the plate 15, which itstrikes at the central depressed port-ion 15, a portion of the waterescaping through the small openings in said portion, but the greaterpart owing over said plate and escaping at its edges. The water droppi ug through the depressed portion falls upon the pan 14 and escapestherefrom through the perforated groove 14b to fall upon the dome 13 andinto the groove or gutter 13?. The pan 14 being formed with its centralportion below the plane of its perforated groove retains at all timessome water on its surface, and is thus protected from the warpinginhuence of the eXtreme heat to which it is subjected.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A water-heater comprising a cylinder, a burner connected with saidcylinder, a dome and a water-pan arranged above said burner and forminga combustion-chamber, and a series of inclined plates arranged withinsaid cylinder and removably supported therein, said plates having formedtherein annular grooves, and perforations for the passage of water andother perforations for the passage of hot air, substantially as setforth.
